How can I fetch data in Vue.js when the route changes?

You can use the beforeRouteEnter or beforeRouteUpdate navigation guards to fetch data when the route changes.

Can you show me an example of using beforeRouteUpdate?

Sure! In your component, you can add:

beforeRouteUpdate(to, from, next) {
  this.fetchData(to.params.id);
  next();
}

What if I want to handle loading states while fetching?

You can set a loading state before fetching and reset it after the data is fetched. Use a data property for that.

Thanks! Is there a way to handle errors during the fetch?

Yes, you can use a try-catch block in your fetch method to handle errors and update your UI accordingly.
